Colorado Cousins of our Kansas Native Plants

Posted on July 14, 2021 by Lorna Harder

Hikers passing through high elevation mountain meadows often catch glimpses of a number of familiar flowers. In fact, many of the mountain meadow natives are closely related to our Kansas native plants.

With nearly daily rain showers, the subalpine grassland meadows of the southern Rocky Mountains are bursting with wildflowers this summer. Rocky Mountain subalpine wildflowers are adapted to high elevations with cooler, shorter summers, longer, colder winters, and intense sunlight. Small, silvery, sun-reflecting, hairy leaves, ground-hugging growth habits, and clumps of showy pollinator-attracting flowers help these Colorado species survive. With a short growing season, flowers are produced and set seed in what seems like record time.

Kansas natives often share similar adaptive features—silvery, fine, hairy, leaves, and similar pollinator-attracting showy flowers –enabling them to survive Kansas’ long, hot summers and cold, dry winters. Although time and physical barriers have separated most Colorado and Kansas native plants into unique species, a few remain as a single species. Let’s take a look at a few of these Colorado cousins.

Columbine (Aquilegia spp)

Kansas’ wild columbine (Aquilegia canadensis) blooms during the cooler, moister spring months of the year, and seed is immediately dispersed. Blue columbine (Aquilegia coerulea) – Colorado’s state flower – blooms in July, taking advantage of the sunshine and warmer days of summer in the high mountains.

Yarrow (Achillea millefolium)

Yarrow (Achillea millefolium) doesn’t change species between Kansas and Colorado, but the blooming time does! While yarrow blooms in late spring in our Kansas prairies, in subalpine mountain meadows, it blooms in July, taking advantage of the sunshine and pollinators of mid-summer. There is little chance that, should they be grown together, cross-pollination could occur between these quite different ecotypes.

Prairie Smoke (Geum triflorum)

Prairie Smoke (Geum triflorum) is another wildflower species that remains the same from Kansas to Colorado. Again, the time of flowering differs. Kansas individuals bloom in spring, and Colorado individuals bloom during similar temperature conditions that occur at the height of the high altitude summer.

Alpine Parsley (Pseudocymopterus spp.)

Members of the carrot and parsley family are commonly found in both Kansas and Colorado. Golden Alexanders (Zizia aurea) grace our gardens in spring, while high mountain meadows are filled with the yellow umbels of mountain parsleys in July.

Primrose (Oenothera spp)

The white, night-blooming showy evening primroses (Oenothera speciosa) typically appear in May and June in Kansas. Come July, their diminutive Colorado cousins, (Oenothera spp) make their appearance in rocky niches and along trails.

Locoweed (Oxytropis spp.)

Locoweed (Oxytropis spp.) fills Colorado mountain meadows with patches of bright pinks, blues and lavenders. Like the wild indigoes (Baptisia spp) that brighten Kansas prairies and pastures, locoweed is a nitrogen-fixing legume. Both are also toxic to cattle, sheep and horses.

Ragwort (Packera spp.)

Ragworts (Packera spp.) are delightful yellow flowers of shade and sun. Colorado’s ragworts are commonly found along a trail’s edge in July. Kansas’ golden ragwort (Packera plattensis) is one of the first wildflowers to brighten winter-weary landscapes in April.

Penstemon (Penstemon spp)

Penstemons (Penstemon spp) are abundant in the Rocky Mountain subalpine meadows in July. Generally short in height and with smaller flowers, they nonetheless add deep, rich lavenders, blues and purples to rocky niches and trailsides. Their taller Kansas cousins precede them, blooming in late spring.

Jacob’s Ladder (Polemonium spp.)

Hike through a subalpine, shaded, moist forest, and suddenly you may encounter a faint scent of skunk, indicating that you have stepped on Jacob’s ladder, a lovely blue-flowered species that hugs the ground with ladder-like leaves. In Kansas, Jacob’s ladder (Polemonium reptans) is a woodland spring ephemera with striking blue, bell-shaped flowers, and yes, the scent of skunk!

Shrubby cinquefoil (Dasiphora (Potentilla) fruticosa)

Shrubby cinquefoil (Dasiphora (Potentilla) fruticosa) is commonly found in high mountain meadows in July. It is just one of a number of cinquefoils that commonly grow at high elevations. Bright yellow flowers attract numerous pollinators. In Kansas, prairie cinquefoil (Dasiphora (Potentilla) arguta), also a shrub, blooms in scattered clumps throughout the summer.

Goldenrod (Solidago spp.)

Our Kansas goldenrods tend to be taller, filling the late summer prairies and pastures with swaths of yellow. They are the harbingers of autumn, blooming in late August and September. Subalpine goldenrods can’t wait that long. The diminutive Rocky Mountain goldenrod begins to flower in mid-July in the high montane meadows, adding their golden color to the seasonal procession of color.

These are just a few of the many familial relationships that exist between Kansas and Rocky Mountain native plants. Next time you travel west, take a moment to find a familiar “face” in the wildflowers at your feet!

Celebrating Earth Day Through Native Plants

Posted on April 22, 2020 by Brad Guhr

Today is the 50th Anniversary of Earth Day. For a half century, April 22 has been a day when we celebrate a connection with our planet and pause to think about how we can be better earth stewards. I would like to state the case for having native plants be central to this stewardship focus.

Earth Day in 1970 mobilized 20 million Americans to unify in support of environmental protection. The energy of this movement led to a greater awareness of and protection for natural elements important to humans, including clean air (Clean Air Act of 1970), clean water (Clean Water Act of 1972) and biological diversity (Endangered Species Act of 1973).

My 50th Anniversary Earth Day Flag – an adapted version of John McConnell’s Earth Day flag adorned with the spring blooming native plants (clockwise from upper left-golden alexander, vernal witch hazel, Missouri evening primrose, and rose verbena).

Native plants and their ecosystems are closely connected to the health of air, water, and biological diversity. Native plants photosynthesize, produce oxygen and sink atmospheric carbon. Native plants buffer streams, hold soil, and filter moving water. Native plants provide food and habitat for wildlife of all kinds. For the more than one billion people that will recognize Earth Day around the world today, celebrating native plants could easily be central to this celebration.

So, to celebrate the 50th Earth Day, I would like to recognize some of the spring-blooming native plants that are hitting their stride in my home landscape right now.

Spring blooming wildflowers offer the first signs of hope after a long winter. In late winter/early spring, they bait us with anticipation, even when nighttime temperatures regularly dip below freezing and cold winds are not yet inviting us to be outside. Their root systems receive messages from increasing hours of daylight and higher average temperatures. Their green shoots break dormancy and emerge as if they are responding to cheerful invitations of the robins, repeatedly calling “cheer-up, cheer-a-lee, cheer-ee-o”.

That was the scene in my yard in early March. Fast forward now to mid April through more than a month of pandemic isolation. While I’m captive at home, the need for hope and beauty seems ever greater and the following spring blooming wildflowers are answering the call.

Wild Ginger (Asarum canadense)

Wild ginger is a creeping wildflower that creates growing ground cover colonies. The roots of the plant smell like ginger. Their heart-shaped close-to-the-ground leaves may be less than striking, but the hidden flowers of wild ginger (pollinated by beetles, flies and ants) are worth the search.

Woodland Phlox (Phlox divaricata)

The Greek meaning of the word phlox refers to the intense floral color which is evident once you see woodland phlox in bloom. The plant will form a spreading colony. It does surprisingly well in Kansas if you can find a protected place for it. The fragrant and showy flowers attract butterflies, hummingbird moths, and hummingbirds.

Roundleaf Ragwort (Packera obovata)

Once established, roundleaf ragwort establishes a creeping colony and is one of the earliest bloomers in the spring. Roundleaf ragwort flowers attract butterflies, bees, and bumblebees. With an evergreen leaf throughout all seasons, this species offers year-round interest without being invasive to the detriment of surrounding plants.

Pennsylvania sedge (Carex pennsylvanica)

Pennsylvania sedge is commonly found in the dry to dry-mesic understory of oak-hickory woodlands. It is a nice landscaping choice for a dry, shady yard location in Kansas. While they certainly do resemble grasses in their appearance, sedges, characterized by their triangular stem (“sedges have edges”) are in a family all their own.

Columbine ‘Pink Lanterns’ (Aquilegia canadensis)

Columbine is easy to establish in partial sun to full shade conditions and its flowers attract hummingbirds and bumblebees. The name is in reference to a couple of birds. The genus name Aquilegia is derived from a combination of the Latin word “aquila” (meaning eagle for the five spurs resembling an eagle claw) and the Latin word for “columba” (meaning dove, for five doves nestled together). This pink version of Aquilegia canadensis was actually discovered in Marion County, Kansas by Dyck Arboretum of the Plains!

Spring Bloomers in Your Landscape

Many spring blooming wildflowers are native to woodland understories. Such woodland understories historically would have only been native to Eastern Kansas. Today, urban tree canopies and the north side of fences, garages, and houses all provide great shady habitat to plant spring woodland bloomers like those featured in our FloraKansas plant sale Spring Woodland Kit.

But you certainly don’t need to stop with the species in this kit. See a previous blog post (Spring-Blooming Prairie and Woodland Plants) featuring additional spring bloomers that you might consider for shady or sunny areas.

Celebrate Earth Day with me. Consider participating in the rewarding ritual of native plant gardening and make every day Earth Day.

Shade plants worth trying

Posted on April 21, 2015 by Scott Vogt

There is always that area in your landscape that is shaded. These areas can be frustrating, because they don’t grow turf well leaving the soil bare. Here are a few good shade plants to spruce up that dark corner of your garden.

Columbine, Aquliegia canadensis

Delicate but tough wildflower for the shade garden. Flowers are red with yellow that bloom in April and May. Plants ultimately reach 12-24 inches tall in part-shade to shade. They are quite adaptable, but prefer an average to moist soil.

Appalachian Sedge, Carex appalachica

This sedge looks like it came straight from the 80’s big hair days. The punked out spikes reach 12 to 18 inches straight up in any shade garden. This lovely sedge is native to dry woods. Its fine texture and fountaining habit make it a lovely groundcover in dry shady sites, even in the root zone of trees.

Woodland Phlox, Phlox divaricata

This native phlox is a favorite spring wildflower. It can be found along streams and in open woods. The 12 inch clumps are covered with delicate 1.5 inch lavender flowers in May. Quick to fill in areas when happy, it requires little or no maintenance.

Epimedium ‘Lilafee’

This dwarf Epimedium grandiflorum is one tough cookie in the landscape. In mid-spring, the new ear-shaped foliage emerges with a dramatic bronzy-lavender color. The delicate violet flowers dance above the heart-shaped foliage.

White Woodland Aster, Aster divaricatus ‘Eastern Star’

This nice selection for the woodland border has pure clean white flowers atop the mahogany stems. It blooms in September and October, adding splashes of color to your shade garden later in the season. It prefers part-shade to shade in an average to moist soil. It is a weaver that slowly fills open areas, but it is not aggressive.
